I'm using the greet_pause feature in Sendmail 8.13 to delay giving the smtp
banner by a couple of seconds.  It's a great anti-spam tool.

Unfortunately, it's confusing hobbit:

Service smtp on tolstoy.denmantire.com is not OK : Unexpected service
response


554 denmantire.com ESMTP not accepting messages
550 5.0.0 Command rejected
221 2.0.0 denmantire.com closing connection

If hobbit had waited 2000 milliseconds after the connection before trying to
send, it would have worked just fine.  Is there any way to insert a small
delay there?

I setup my sendmail access file to not have a greeting pause for my 
internal machines (including hobbit).

GreetPause:127.0.0.1            0
GreetPause:(IP of hobbit)       0

This way there is no delay for my "friends".

Hah!  Did not know you could do that in access.  That's absolutely perfect -
thanks much!

AHA!  Thanks.  I expected the "expect" behavior of waiting for the 220
string before sending the command strings.  This is a great tip.
